Method for manufacturing material e.g. solid cellulose acetate-triacetin-filament used for manufacturing filter rod for tobacco processing industry, involves evaporating solvent so that solid cellulose acetate-triacetin-filament is obtained

摘要

#CMT# #/CMT# The method (10) involves producing cellulose acetate-acetone-triacetin solution (17) from cellulose acetate (14), acetone (15) and triacetin (16), where a percentage weight of the triacetin in the solution is 1 percentage relative to a weight percentage of the acetate. The solvent is evaporated so that a solid cellulose acetate-triacetin-filament (23), a cellulose acetate-triacetin-granulate (25) and a cellulose acetate-triacetin-filter tow (28) are obtained. An evaporated acetone-air mixture (20) is recovered and returned into a process. #CMT# : #/CMT# Independent claims are also included for the following: (1) a material (2) a method for manufacturing filter rods (3) a filter manufacturing machine. #CMT#USE : #/CMT# Method for manufacturing a material e.g. solid cellulose acetate-triacetin-filament, cellulose acetate-triacetin-granulate and cellulose acetate-triacetin-filter tow, which is used for manufacturing a filter rod for a tobacco processing industry (all claimed). #CMT#ADVANTAGE : #/CMT# The method allows a higher amount of the triacetin to be homogeneously introduced into the filter rod without occurrence of adhesion effect of the triacetin in a filter rod machine, and provides harmless contact of the cellulose acetate-triacetin-filament at an outer surface of the filter rod. The method allows a desired proportion of the triacetin ranging from 8 to 10 percentage of a filter rod weight to be maintained in the filter rod without problems. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view illustrating a method for manufacturing a material and a filter rod. 10 : Method manufacturing a material 14 : Cellulose acetate 15 : Acetone 16 : Triacetin 17 : Cellulose acetate-acetone-triacetin solution 20 : Evaporated acetone-air mixture 23 : Solid cellulose acetate-triacetin-filament 25 : Cellulose acetate-triacetin-granulate 28 : Cellulose acetate-triacetin-filter tow.
